Embodiment Construction

[0017]FIG. 1 shows an exemplary hybrid system 1 which is mounted in a hybrid vehicle. The hybrid system 1 has two types of driving power sources: an engine 11 serving as an internal combustion engine, and a motor 12 serving as an electric motor. The hybrid system 1 controls the driving of the vehicle in various kinds of travel modes used in combination depending on travel conditions. As examples of the travel modes, a mode in which the driving power of the engine 11 is mechanically translated to wheels, a mode in which the vehicle travels only using the motor 12 while the engine 11 is stopped, a mode in which the driving power of the engine 11 and the driving power of the motor 12 are translated to wheels, a mode in which the vehicle travels by generating electric power with the motor 12 and collecting the electric power, and / or the like, are provided.

[0018]The hybrid system 1 may include a battery 16 including an electric cell module as an electric charger and a charging connector ...

Abstract

Driving support apparatus, methods, and programs are provided for a hybrid vehicle whose driving power sources are an internal combustion engine and an electric motor operating with electric power supplied from an electric charger. The hybrid vehicle includes a hybrid control device for controlling the internal combustion engine and the electric motor. The apparatus, methods, and programs store travel history data of the hybrid vehicle, calculate a position of the hybrid vehicle, and determine whether a destination is set. If a destination is not set, the apparatus, methods, and programs predict a destination based on the travel history data, and calculate a degree of reliability of the predicted destination based on the travel history data. The apparatus, methods, and programs control the hybrid control device based on the calculated degree of reliability.

Description

INCORPORATION BY REFERENCE[0001]The disclosure of Japanese Patent Application No. 2007-082690, filed on Mar. 27, 2007, including the specification, drawings and abstract thereof, is incorporated herein by reference in its entirety.BACKGROUND[0002]1. Related Technical Fields[0003]Related technical fields include driving support apparatus, methods, and programs for hybrid vehicles.[0004]2. Related Art[0005]Hybrid vehicle employing an internal combustion engine and an electric motor as driving power sources are well known in the art. Such hybrid vehicles store electric power supplied by an external infrastructure in a battery. When the amount of charge remaining in the battery is reduced, the battery is charged by means of a charging station for an electric vehicle or an exclusive battery charger plugged into a house outlet.[0006]According to this type of hybrid vehicle, when the amount of charge remaining in the battery goes below a low threshold value while the vehicle is traveling, ...
